Specification of Letters Patent.

Application filed September 23, 1912. Serial No. 721,934.

To all whom it may concern:

Be it known that I, GUSTAV TORDAY, acitizen of the United States, residing at South Bethlehem, in the county of Northampton and State of Pennsylvania, have invented a new and useful Gearing, of which the following is a specification.

The device herein disclosed is an improvement in transmission gearing for motor vehicles.

One object of the present invention is to provide a. device of the type above mentioned, having three forward speed and a reverse.

Another object of the invention is to pro-' vide a device of the type above described, in which the different speeds, and the reverse, are accomplished by means of a lost motion, created by novel combination of elements.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made withinthe scope of what is claimed Without departing from the spirit of the invention. In the drawings :-Figure 1 shows the invention in longitudinal section; Fig. 2 is a transverse section on the line 2--2 of Fig. 1; Fig. 3 is a transverse section on the line of Fig. 1; Fig. 1 is an elevation of one of the yokes; Fig. 5 is an elevation of the bell crank; and Fig. 6 is a longitudinal section of a portion of the driven shaft, the view depicting the means whereby the collal's are held upon the shaft.

The structure herein disclosed will be found of peculiar efliciency in transmitting motion under a constant load.

In carrying out the invention there is provided a casing, denoted generally by the numeral 10,- the casing 1?) comprising main member 11 having a flange 19., an auxiliary member 15 havinga flange 16. and a ring'le which is bolted between the flanges 12 and 1G. The main member 11 of the casing 10 is provided with a hub 18 in which is mounted a bearing 22 havf a ball race In the rear face of the end Wallcf the hub 18 element, is denoted by the numeral 16' and.

,coiiperating with the ball race 21, and receiving balls 20.

A driven shaft 33 extends longitudinally.

of the casing 10 and terminates at its forward end within the hub 28 of the drive shaft 16. .The forward end of the driven shaft 33 carries a bearing 32, cooperating with balls 31 mounted to rotate Within a bearing 30 which is secured within a recess 29 formed in the hub 28 of the head 17.

The auxiliary member 15 of the casing 10 is equipped with a hub 47 having a recess 51 in which is mounted a bearing 51 having a race 52,-receiving balls 50, cooperating \vitha race 49, formed in a bearing 48 which is located in the recess 51. The bearings 51 and 48 abut against a thrust member 150, held in the recess 51 by means of a closure 151 which is secured to the hub 47 of the auxiliary member 15 of the casing. The rear end of the driven shaft 33 is thus supported for rotation in the casing 1.

Located to the rear of the head 17' is an annular member 39, having a flange which surrounds the flange 27 of the head 17. In the flange 40 are a plurality of radial openings 11, receiving balls 38 which register in a race 37 fashioned in the outer face of the flange 27 of the head 17.

Secured to the rear face of the annular member 39, is an annular flanged element 81, supporting balls 82-, registering in open;

ihgs 83 which are formed in the periphery of an annular member 80, resembling the annular meu'iber 39. v

Secured to the rear face of the annular Patented Apr. 8, 1913.

member 80 is an annular, flanged element 91,

abut against the body portion 106 of the thrust 105, the springs 109 being overhung by the flange 107. .The springs 109 at their rear ends abut against the ring 14.

The balls 38 which are supported. by the head 17 engage with the Wedge face 43 of a ring 43. The bails 82 engage with the wedgeface of a wedge ring 84, and compression springs 85 are-in terp0sed between the wedge rings 43 and 84. .The wedge faces of the rlngs 43 and 84slope inopposite directions. In the peripheries of the wedge ring 43, of the wedge ring 84, of the annular element 92, and of the thrust member 105, but not in the periphery of the ring 94, are formed transverse grooves 44, registering with grooves 44- fashioned in the inner face of the main member 11 of the casing. Mounted in the grooves 44 and 44 are rods 45, held againstelongitudinal movement by the ring 14 and by suitable projections 45 upon the main member 1.1 of the housing. It will be understood that rods 45 serve to prevent the elements 43, 84,92 and 105 from rotating independently of the casing 10.

In the hub 28 of the head 17 there is fashioned a recess 35, having radial extensions 36. These elements and Elbconstitute one member of a clutch. In the annular member 39 there is formed a recess 42 having radial extensions 42", the elements 42 and 42 constituting a clutch member sin1i-- lar to the clutch member Bil-36 which is formed in the head 17. In the annular member 80 there is formed a clutch element 152 which is similar to the clutch 42-42 and. 3536, hereinbefore described. There is a clutch 101 in the ring 94. i

The invention further includes a clutch 90 formed integrally with a sleeve 59, adapted to slide longitudinally of the driven shaft 33, the clutch 90 being adapted to register in the clutch member 35-36, or in the clutch member 42-42. By referring to, Fig. it will be seen that the sleeve 59 is received Within transverse slots 59, formed at the forward endsof rods 57 and 58, mounted to slide in grooves 55 formed longitudinally in the driven shaft 33. The driven shaft 33 is equipped with longitudinal, radially extended ribs 53 which register in corresponding grooves in the clutch sleeve 59. The rods 57 and 58 are provided adjacent their rear ends with transverse slots 60, receiving a collar 54 provided with trunnions 63, journaled in the arms 65 of a yoke 01 mounted to swing on a pin- 68 which is upheld by the auxiliary part of the casing 10. One arm 7 0 of the yoke 61 is equipped with anen V60 largement 7l,'having functions which will be set forth hereinafter.

A collar 54' is mounted upon the driven shaft 33, the-collar 54"being formed in agrau with the sleeve 87 of a clutch 88, the clutch 88 iaeing ,aclaptcdto register with the the casing 10.

' 90into the driven shaft 33.

mounted to'swing on a pin 07 which is supported by the auxiliary member 15 ofthe casing 10. The yoke 62 is equipped with a boss 69, received within the bifurcations '70 of a bell crank 71, the bell crankbeing journaled on the pin 68. One arm 73 of the hell i, crank 71 is equipped with an enlargement, 72

cooperating with the enlargement 71 of the yoke 61.

1 h. l'dd nally in a bearing 77 formed integrally with the upper portion of the main memberll of The rod 75 is equipped with spaced fingers-74, between which the enlargement 72 of the bell crank 71 is re ceived. Another rod 76 is mounted to slit similarly to the rod. 75,-the rod be equipped with lingers 74 which cnga go the enlargement 71 of the yoke 61. The rods and 70 are equipped with spaced locking notches 153, adapted to receive balls 110 held in an extension 111 of the bearing 77, there being springs 112 in the extensions, which serve to hold the balls 110 in the notches 153, the tension of the springs 112 being regulated by means of screws 114.

When sliding movement is imparted o the rod 76, the fingers 74 thereof will engage the enlargement 71' of the yoke 61 and tilt the yoke on the pin 68, the arms 65 of the yoke engaging trunnions '33 and imparting rectly from the shaft 10 to thedriven shaft 3 33. The driven shaft 33, therefore, will be rotated forwardly, at its highest speed ,Suppose, however, that the rodf'ld has been manipulated as above described, to cause the clutch to register in the clutch member 4242 of the annular member 30. Then as rotatory movement impartial to the drive shaft 16, such motion will be trans inittedinto, the head 17 and from. the head 17., byway of the balls 38, into the annular a manner 75 is mounted to slide longitudb Elli til

member 39, from the annular member 39 by a means of the clutch mechanism 4.53 442 eratio'n, the balls 38 will exercise the tunetions of planet pinions and roll upon the fixed During this ring 43 the springs 85 servin to maintain the wedge ring 43 engaged wit the balls 38. Owing to the cotiperative relation existing between the balls 38 and the ring 43, the driven shaft 33 will be rotated at a less speed than that occurring wI en the driven shaft is directly conn cted with the drive shaft 16'. Suppose that e rod 76 is manipulated until the clutch 90 stands in the ositlon shown in Fig; 1, the clutch 90 -un er such. circumstances, being disconnected from the head 17 and from the annular member 39. If, now, the rod 75 bemanipulated, the fingers 74 thereof, engaging the enlargement 72 upon the arm 73 of the bell crank 71 will tilt the bell crank 71 on the pin 68, the fingers 70 of the bell crank engaging the boss 69 of the yoke 62, the yoke 62 tilting on the pin 67 and engaging the trunnions' 64 of the collar 54:, the collar 54 and the clutch mechanism 87- -88 being advanced, until the clutch ele ment 88 cooperates with the clutch element 152 which is formed in the annular member 80. Then the drive will take place from the. shaft 16 into the head 17, thence into the balls 38 and into the annular member 39, and from the annular member 39 into the annular member 81, and from the annular member 81, by way of the balls 82, into the annular member 80, and thence into the clutch 88 and into the driven shaft 33.

vspeedthan that occurring when the balls 38 only act as planet pinions, ashereinbefore described. Let it .be supposed, again, that the clutch 90 stands as shownin Fig. 1, the

rod 76 being actuated to move the collar 5 1" until the clutch 88 engages the element 101 in the ring 94. Then drive will take place from the shaft 16' into the head 17, and thence by way of the balls. 38 into the annular member 39, and from the annular member 39 into the flanged element 81, and then by way of the balls 82, into the annular member 80, and from the annular member} 80 by Way of the flanged, annular element 91 into the balls 93. The balls 93 are held for rotation in the annular element 92 ich, in its turn, is prevented from rotatlon, by means of the rod 45. The balls 93, acting upon the inner periphery of the flange 97 of the ring 94, will impart a reverse rotation to the ring 94, to the clutch 88 and to the driven shaft 33, the reverse,'therefore, taking place at the lowest of the three speeds.

Having thus described the invention what is claimed is 1. A power transmitting mechanism including a drive shaft; a drlven shaft; annular members; means for clutching one annular member to the driven shaft; a planet pinion motion connection between one annular member and the drive shaft; and a planet pinion connection between the annular members. i
